Genghis Khan and his troops may have unwittingly used more than just brute military force to conquer entire nations and to establish the infamous Mongolian empire. A report in the October issue of Genome Research suggests that Genghis Khans invasions spanning the continent of Asia during the 13th century may have been a primary vehicle for the dissemination of one of the worlds most deadly diseases: tuberculosis.
In this study, a team of scientists led by Dr. Igor Mokrousov from St. Petersburgs Pasteur Institute demonstrated that the evolutionary history of the causative agent of tuberculosis (TB) has been shaped by human migration patterns.
The researchers examined the genetic signatures of over 300 strains of Mycobacterium tuberculosis, rod-shaped bacteria that, when airborne, infect the pulmonary systems of vulnerable individuals and give rise to clinical TB. The World Health Organization (WHO) estimates that TB kills 5,000 people worldwide every day, or approximately 2 million people each year. The pathogen is rapidly spreading and evolving multi-drug resistant strains in susceptible regions such as Africa. Interestingly, a strong gender bias in TB infection is reported globally each year; a 70% excess of male TB cases is typical.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
